Python 3.7.3 from Anaconda3 cannot make https request or import ssl #19
Description
I am running a python script using python 3.7.3 from Anaconda 3 installed a week ago. It could not make https request to a simple website like https://www.bing.com with the following error. The python is called from cgi in IIS web server.

To troubleshoot, I added "import ssl" in the code, it threw an error as below. However, in conda prompt, there was no error with import ssl, and it points to the same ssl.py.
A problem occurred in a Python script. Here is the sequence of function calls leading up to the error, in the order they occurred. I tried this with 32bit and 64 bits Anaconda installation and had the same problem.
C:\inetpub\wwwroot\demo\myForm.py in ()
82 import sys
83 #import dateutil
=> 84 import ssl
85
86 #---------
ssl undefined
C:\ProgramData\Anaconda3_x64\lib\ssl.py in ()
96 from enum import Enum as _Enum, IntEnum as _IntEnum, IntFlag as _IntFlag
97
=> 98 import _ssl # if we can't import it, let the error propagate
99
100 from _ssl import OPENSSL_VERSION_NUMBER, OPENSSL_VERSION_INFO, OPENSSL_VERSION
_ssl undefined
ImportError: DLL load failed: The specified module could not be found.
args = ('DLL load failed: The specified module could not be found.',)
msg = 'DLL load failed: The specified module could not be found.'
name = '_ssl'
path = r'C:\ProgramData\Anaconda3_x64\DLLs_ssl.pyd'

Note that I also had to update numpy to make the import work for 64bits version, but updating openssl to 1.1.1b did not help.
